I know how it evolves in the base games, but in Lets Go it doesn’t have friendship is a mechanic, just affection. It also doesn’t have a day/night cycle. So how do you evolve it in the second kanto remakes?
Alolan Meowth evolves into Alolan Persian when leveled up with high friendship. In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, Alolan Meowth evolves into Alolan Persian starting at level 28.
